Email Header Analyzer

Paste raw email headers. See the full hop trace and authentication results, right in your browser.

No signup required

Paste the raw Internet headers of any suspicious email. We parse every Received: hop, surface the relay IPs, and decode SPF / DKIM / DMARC / ARC results, all in your browser.

In Gmail: open the message, click the three-dot menu, then "Show original". In Outlook: open the message, then File > Properties > Internet headers.

These free tools are a fraction of what Claro does. Run phishing simulations, deliver bilingual training, and report to OJK / ISO 27001 / PDPA from a single dashboard.
